New Game - Three Card Poker

[Switch1995]

99ers: A few months ago I was looking for an app to play three card poker and didn't find one I liked, so I decided to write it in XB.   For those unfamiliar with the game, there are a bunch of videos on youtube:

 

 

Basic strategy is to play when you hold an Q-high or better and fold anything below that. 

Even after several hours of free cocktails, you can still maintain perfect strategy ;).   

This is also one of the only poker games where a straight beats a flush.  The three best hands are straight, 3 of a kind and straight flush and the TI-99 will show it's appreciation when you get them.  Enjoy!

 

Req: Extended Basic, 32k

Updated version: THREECARD

For some reason this downloads as executable "HREECARD"...but still works in Classic99

Hi Switch1995,
I have been playing your game for a while and I find it very nice, actually missing this poker variant on TI99!

I have also have added it to the TI99iuc's Database and I hope you don't have anything against it 😛

 

I do have some questions for better understanding though:

 

- I had understood that the bet on 'Pair Plus' was not mandatory instead on this version it is, can you confirm?

 

- I had understood that if the Dealer does not possess at least one Queen as the highest card, he could not make the match, instead here he does anyway, confirm that this is normal?

- I also have tried entering value 0 to the bets but it exits the game to TI BASIC with an Error.
Maybe this feature could be fixed anyway?

 

ok, that seems to be enough 😛

Thanks again for this game.

Hi ti99iuc,

 

I'm so happy you are enjoying the game and no problem with adding to your database.

Yes:  In a real casino, the "Pair Plus" is optional.  I took a bit of liberty to make it mandatory to make my payoff algorithm and "Display at" statements a bit simpler.  Plus, I figured with fake money, people would want to gamble a bit!  I also strategically made the minimum bankroll ($500) at least three times as large as the maximum bet ($100) to allow the main play loop to not crash from the start.  In a real casino you could have a bankroll of $1010, put $1000 on the pair plus bet, $5 on the ante and $5 on the play and pray for trips!!

If the Dealer does not have a Queen-high or better the Ante bet pays, but the Play bet is a push.  The Pair Plus is always in play no matter the Dealer's cards.  For the hand you are showing, these are the correct payoffs.

Interesting.  I thought the ACCEPT AT checked the value and just went back to the same line.  I'll have to take a look.  Thanks again for the feedback!

Dealer will win 75% of the time over time.

[GDMike]

That's supposed to happen like 1 player can win 100 percent on a single game.

[Switch1995]

House edge is 5.32%.  About equal to American (double zero) roulette.  Craps and Blackjack are much better games if you are trying to lose less money.

I found the issue. When I renumbered my subprograms I broke some code that was already tested.  The attached version will not allow you to enter a value outside of the min-max values.  Thanks again for the catch.  *If a moderator could swap this file with the initial post that would be awesome.  Otherwise, the only issue is this value check.  The game plays fine otherwise*

Happy to help a friend and thank you for the update instead.
I also have swapped it on the ti99iuc page.

I have also found the first two REM lines missing in this Last Update and I have added them again in the final file. Well this is just because I like to have the listing complete as in original 😛

I also have tested again the game and it is perfect now. Nice addicted game to the collection

The odds on this make Roulet or the big wheel look like a good bet.

The fact that PUSH and how it forces you to bet more money than is sane.

This has better odds for the house then almost any other game in gambling.

I look at it in "tiers":

 

There is the serious "I'm here to win money"/big money tier:  Blackjack (0.28% house edge), Baccarat-bet on Banker (1.06%) and Craps-Pass/Come lines (1.41%)

 

There is the "I'm here to have fun, probably lose, but maybe win" tier:  Let It Ride (3.51%), Caribbean Stud (5.22%), Roulette-American (5.26%) and Three-Card Poker: even money on all three bets (5.32%)

 

Then there is the "I'm a pure dreamer and am not expecting to win, only want a jackpot":  Slots (~10-15%), Big Wheel (22.22%), Keno (25-29%)

Done.

Mini Royal Flush...dealt in order....playing $100 a hand just after buy-in...and Dealer qualifies.   Why can't this happen IRL???

 

[GDMike]

Good job

Some casinos will pay 50-1 for the mini royal but they then pay the straight 5-1, which makes the overall odds worse for the player.
